Patented Dec. 4, 1934 UNITED STATES PATENT OFFICE h 1.92:3,654 7' v A WINDOW OPERATING Dav es Arthur Straker; New York, N. Application August 29, 1932,;Serial No. 630,793 1 Claim-I (01. 292-265) The invention is a device for opening and closing the upper and lower sash of windows which provides readily detachable handles at both sides of the window and which also provides l i a lock for locking the window sash in any position.

.The object of the invention is toprovide means for opening and closing the upper sash of a window without raising or lowering the lower sash.

Another object of the invention is to provide means for locking window sashes so that they may remain open in any position to provide ventilation.

Another object of the invention is to provide a device for operating the upper sash of windows which may be used without screws or the like. A further object of the invention is to provide a device for opening and closing the upper sash of windows which may readily be removed and replaced.

And a still further object of the invention is to provide means for opening and closing the upper sash of a window which is of a simple and coonomical construction.

With these ends in view the invention embodies two comparatively straight members with notches in their inner sides and projections from their upper ends, and sockets adapted to be placed upon the window sash and in which the projections at the upper ends of the straight members may be held.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a view showing one side of a window with the device installed thereon;

Figure 2 is a detail showing an enlarged view of the device.

Figure 3 is a detail showing the clip at the upper end of the device.

Figure 4 is a plan view of the clip at the upper end of the device.

Figure 5 is a view showing the face of the socket.

Figure 6 is a general view of the socket.

Figure 7 is a view showing'the device as it 5 would appear in use when looking the sash.

Figure 8 is a detail showing an alternate means of installing the device.

Figure 9 is a detail showing a window of an alternate construction in which the clip may be 5 directly held in an opening in the sash.

In the drawing the device is shown as it would be made wherein numeral 1 indicates a straight member which will be hereinafter referred to as the stick, numeral 2 the clip at the upper end of 55 the stick, and numeral 3 the socket.

The stick 1 may be made, as shown in Figure 2; of astraight piece of material, preferably of a rectangular shape and it will be noted that notches l may be provided in the inner side with their upper 'ends straight and their lower ends bevelled These notches may be arranged in any position and as many as may be desired may be provided. Another notch 5 is provided at the lower end of the stick which will fit over the upper edge of the lowersash to lock the window in the :closed position asshown in Figure 1. It will be understood that this stick may be of any shape or size and the openings therein may be located in any desired positions.

The clip 2 may also be formed at the upper end of the stick by any means and may be of any desired shape or size. In the design shown the clip 2 is formed of a flat bar which extends forward from the stick, as shown in Figure 4. and the end of the bar is bent at right angles and provided with a projection 6 having a narrow portion 7 therein and this is shaped so that the projection 6 may be placed thru an opening 8 in the socket 3 when the stick is held in the position shown by the dotted lines 9 in Figure 7. It will be noted that as the stick is lowered to the upright position, as indicated by the full lines in Figure '7, the projection 6 will be locked in the opening 8 and it will be impossible to removethe stick without again raising it to the position shown in dotted lines. It will be understood that the projection 6 may be of any other shape or design which is adapted to be held in an opening in a socket that may be located. at the upper portion of the window sash.

The socket 3 may be made, as shown in Figure 6, with prongs 10 that may be inserted between the glass and head of the sash, at one side and a plate 11 with additional prongs 12 at the other side with the prongs 12 bent slightly inward so that they may be forced into the surface of the window sash, as shown at point 13 in Figure 1. The socket may be held in position by screws placed thru openings 14 therein or by any other means. The socket may also be of any other shape and arranged in any manner desired.

In the design shown in Figure 8 the socket is formed of an angular shaped plate 15 which may be held to a metal sash 16 by a screw 17 and the screw 1'7 may be held by an expanding nut 18 which may be placed thru an opening 19 in the sash. It will be understood that a clip of any other design may be provided and it may be held to the sash by any other means.

In the design shown in Figure 9 a metal sash is shown and an opening 20 is provided in the sash which may be of the same shape as the opening 8 in the socket 3 so that the projection 6 of the clip 2 may be inserted therein and the socket 3 dispensed with. It will also be understood that the upper end of the sticks may be held in the sash in any other manner.

It will be understood that other changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the use of any other material for forming the stick 1 instead of wood as shown, another may be in the use of any other means for providing a projection at the upper end thereof, and still another may be in the use of any other means for holding the projection to the sash.

The construction will be readily understood from the foregoing description. In use the device may be provided and installed as shown and described and it will be noted that when it is desired to lower the upper sash the sticks 1 may be held outward and by pulling downward with both sticks the upper sash may be firmly gripped and drawn downward. The sash will be automatically locked in any position and it will be noted that the bevelled edge of the lower end of the openings 4 will grip the under side of the upper edge of the lower sash to prevent closing the sash without holding the sticks outward. The device, therefore, provides means for raising and lowering the upper sash and also a positive lock to hold the sash in any position and to prevent the sash being opened or closed from the outside.

The device may also be used to raise the lower sash, as the upper sash may be lowered until one of the notches 4 catches under the upper end of the lower sash and then as the device is pushed upward the lower sash will move upward also. The device will therefore open and close both the upper and lower sash and also lock both of the sash.

Having thus fully described the invention what I claim as new and desire to secure by Letters Patent, is:

The combination with a double hung window having an upper and a lower sash; of a bar having notches in one side thereof adapted to engage the upper and lower surfaces of the cross member at the upper end of the lower sash with the bar resting against said member, said bar having a right angle extension at its upper end with a projection extending at right angles from the end of said extension, and said upper sash having a socket in the upper outer corner thereof adapted to removably hold said projection.

ARTHUR STRAKER.
